Go version returns unknown, gccgo fails

Question

I installed gccgo using:

sudo pacman -S gcc-go

When I tried building my code using go build -buildvcs=false -compiler gccgo ., the following error was returned:

# github.com/CompeyDev/nemo/prisma/db
gccgo: fatal error: Killed signal terminated program go1
compilation terminated.
note: module requires Go 1.19

So, I ran go version which returned go version unknown linux/amd64; note the "unknown". I have no clue how the version can return unknown.

Thanks to @JimB pointing out how the arch gcc-go package was compatible with version 1.18 only, I was able to downgrade go, and this fixed the compilation issue. However, now I have a new error:

# github.com/CompeyDev/nemo/prisma/db
gccgo: fatal error: Killed signal terminated program go1
compilation terminated.
